Does the punctuated equilibrium theory refute evolution?

Introduction

Both creationist and intelligent design writers assert that there are large gaps in the fossil record, and that the conventional scientific picture of a gradual evolution is a myth. To a certain extent, this is true: the fossil record includes transitions that appear abrupt. In 1972, paleontologists Niles Edgredge and Stephen Jay Gould published

The great silence

As we have explained in previous Math Scholar blogs (see, for example, MS1 and MS2), the perplexing question why the heavens are silent even though, from all evidence, the universe is teeming with potentially habitable exoplanets, continues to perplex and fascinate scientists. It is one of the most significant

String theory, fine tuning and the multiverse

String theory is the name for the theory of mathematical physics which proposes that physical reality is based on exceedingly small “strings” and “branes,” embedded in 10- or 11-dimensional space. String theory has been proposed as the long-sought “theory of everything,”

Fermi’s paradox and the Copernican principle

Distant galaxies magnified by a gravitational lens

Fermi’s paradox

As we have discussed on this forum before (see, for example, previous Math Scholar blog), Fermi’s paradox looms as one of the most profound and puzzling conundrums of science: Given that the universe is presumed to be teeming with intelligent life and technological civilizations, why

Chromosomes, DNA and human evolution

History

The Yunis-Prakash diagram comparing the chromosomes of humans, chimpanzees, gorillas and orangutans

Evolution in general and human evolution in particular continue to be bones of contention, so to speak, as evidenced by the ongoing efforts by some groups to prohibit or downplay evolution, or to mandate “equal time” for “intelligent design,” in state and

Pinker’s “Enlightenment Now”: Humanism and scientific progress

Introduction

Many have read books and articles by renowned Harvard social scientist Steven Pinker. In his 2011 book The Better Angels of Our Nature: Why Violence Has Declined, Pinker cited a huge amount of historical and sociological data to conclude, counter-intuitively to many, that violence has declined “at the scale of millennia, centuries, decades, and
